Analog Devices has introduced RMS power detector ADL5906 which can operate upto 10 GHz and a 67 dB measurement range. ADL5906 TruPwr RMS detector doesn't need balun for frequency tuning. The ADL5906 RF detector is suggested for applications that require an accurate RMS measurement of signal power including communications infrastructure, power amplifier linearization, Point-to-Point and Point-to-MultiPoint, cable, military, satellite, instrumentation equipment and ISM band transmitters.
Requiring only a single supply of 5V and a few capacitors, the new ADL5906 power detector is easy-to-use and capable of being driven with a single-ended or differential input drive. Furthermore, the ADL5906 provides low temperature drift across a broad -55ºC to +125ºC that is highly repeatable from part-to-part, thereby reducing design risk and manufacturing costs, says ADI
Key specifications and features:
Accurate RMS-to-dc conversion from 10 MHz to 10 GHz
Single-ended ± 1dB detection range: 67 dB at 2140 MHz, no balun or external input matching required
Response-independent of waveform types such as GSM/CDMA/W-CDMA/TD-SCDMA/WiMAX/LTE
Linear-in-decibels output, scaled 55 mV/dB at 2140 MHz
Temperature stability of
